VAPORIZER OR CARBURETOR FOR INTERNAL-COMBUSTION ENGINES AND PROCESS OF. VAPORIZING THE MOTIVE FLUID FOR SUCH ENGINES.

Specification of Letters Patent. Patented Aug. 1, 1922.

Application filed October 31, 1917. Serial No. 199,491.

To all whom it may concern:

Be it known that I, JoHN lVinxmsoN, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Vaporizer or Carburetor for Internal-Combustion Engines and Processes of vaporizing the Motive F luidfor Such Engines, of which the following is a specification.

This invention has for its object a vaporizer for internal combustion engines and the process of vaporizing the motive fluid as a hydrocarbon as kerosene and the invention consists in the novel features and in the steps hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing which is a sectional view of a vaporizer or carburetor embodying my invention, the contiguous portion of means for heating the air to be mixed with the motive fluid or hydrocarbon being also shown.

This process for vaporizing the motive fluid for internal combustion engines consists in heating the fluid as hydrocarbon internally by mixing a heated gas as air therewith and thereafter mixing the resultant fluid with air to form the explosive charges.

My invention can be applied to any type of vaporizer or carburetor.

In the drawing, 1 designates the body of the vaporizer or carburetor which is formed with a mixing or expanding chamber 2, an air passage 3 leading to the mixing chamber, an outlet 4 which is connected to the intake manifold of an internal combustion engine, and an outlet as a nozzle 5 having its end opening into the lower part of the mixing or expanding chamber 2, this nozzle being located in the air passage 3 in the usual manner. The nozzle is usually entirely open at its end to permit the free exit of the resultant fluid or gas consisting of a mixture of volatilized, or partly volatilized liquid as hydrocarbon or alcohol, etc., and heated air.

6 is the float chamber in which suificient supply of motive fluid as kerosene or other hydrocarbon or liquid is maintained to hold the level of the fluid near the apex of the nozzle 5, as will be understood by those skilled in the art. 7 designates the float in the chamber 6. As the construction of a carburetor including the float chamber is well known further description is thought to be unnecessary.

9 is the -conduit connecting the float chamber and the passage 10 leading to the nozzle 5, the conduit 9 including a lengthened or extended portion 11 which is here shown as in the form of a coil, in order to provide a sufficient length of conduit between the point where heated air is admitted and the nozzle, to permit the fluid to be properly heated and volatilized. The flow of the motive fluid from the float chamber 6 to the pipe 9 is controlled by suitable means as by the needle valve 12.

13 is the conduit for conducting heated air into the motive fluid prior to the'time it is discharged from the nozzle 5, the pipe 13 communicating withthe pipe 9 near the float chamber 7 and between the valve 12 and the carburetor of the discharge end of the conduit 9.

This pipe and the air passing therethrough are heated by the exhaust gases passing out through the exhaust pipe 14 of the engine and as here shown it is coiled about the exhaust pipe 14 within the jacket 15. The flow of air through the pipe 14 can be regulated by a suitable valve 16.

The fluid, may if necessary, be externally heated before it enters the carburetor or vaporizer, and as here shown, it is so heated while passing through the coils 11 by means of the exhaust gases passing throug a conduit 17 communicating with the exhaust pipe 14 and leading into a jacket 18 surrounding the coils 11, the jacket having an outlet pipe 19. The conduit 17 has a suitable controlling valve 20 therein.

In operation, during the suction strokes of the pistons of the engine, the motive fluid as kerosene with heated air mixed therewith is drawn out of the nozzle 5 in wholly or partly volatilized or vaporized condition, and mixed with air drawn into the chamber 2 through the passage 3, and the mixture is drawn into the cylinders of the engines in the usual manner.

The suction created by the pistons draws the heated air into the pipe 9 which mixes with the motive fluid as kerosene and heats the same internally while said fluid is passing through the elongated portion 11 of the fluid,

- ternally by opening the valve 20 in the .con-

9 to the nozzle 5. For some kinds of it is desirable to also heat them expipe I duit 17, and for others, it is suflicient to heat heating a liquid fuel by them externally only as they pass to the discharge nozzles. My vaporizer is particularly applicable. for rendering volatile motive fluids which first mixture is discharged from the confined passage, substantially as and for the purpose described.-

'2. A vaporizer for internal combustion engines comprising abody having a mixing chamber, a passage for the liquid fuel having a nozzle discharging into said chamber .and an airinletdischarging into the passage for the liquid fuel at a point remote from the end of the nozzle, substantially as and for the purpose specified.

1 In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 16th day of October, 1917.
